What do witches and wizards actually dream about when they fall asleep? In the Wizarding World, a dream can predict the future, connect two minds, reveal someone else's memories, deliver a physical object, or even become a weapon powerful enough to get someone killed. Falling asleep in Harry Potter is surprisingly dangerous.

In today’s Hogwarts lesson, we explore the different types of dreams in the Wizarding World—from normal and prophetic dreams to Voldemort's connection with Harry, Occlumency, dream communication, Dream Messengers, and the mysterious King's Cross limbo between life and death. Turns out, in Harry Potter, a dream isn't always just a dream.
